Building desktop app, using transparent background, using JQuery/UI for drag capabilities.
When my app starts up, all is good, when I drag it, it looks fine but in the initial starting position is left a burnt in transparent shadow in the image of what I've moved.
It never goes away!
Looking at my code in Safari/Firefox etc I have no problem with the dragging, there's no imagery or burnt in shadow left behind.
Any ideas why? I tried to hide my div at the start and then unhide it seeing if that was the case (as I have some other hide/showable divs that don't leave anything behind..)
Using the code at the bottom here:
Will solve that problem, then there is no artifact left behind. Plus you can move it across screens (if you have > 1 monitor connected) and the CPU utilization is WAY WAY less.
Problem at the moment is its quite "jaggy" seems to get a bit confused if you move the mouse around fast.. so doesn't look so great..
To be continued.
